Homocysteine induced cardiovascular events: a consequence of long term anabolic-androgenic steroid (AAS) abuse

Abstract: Objectives: The long term effects (.20 years) of anabolic-androgenic steroid (AAS) use on plasma concentrations of homocysteine (HCY), folate, testosterone, sex hormone binding globulin (SHBG), free androgen index, urea, creatinine, haematocrit (HCT), vitamin B12, and urinary testosterone/ epitestosterone (T/E) ratio, were examined in a cohort of self-prescribing bodybuilders. Methods: Subjects (n = 40) were divided into four distinct groups: (1) AAS users still using AAS (SU; n = 10); (2) AAS users abstinent … Show more

“…The same results were also demonstrated in a recent meta-analysis including 51 studies on men with low or low-to-normal plasma testosterone levels who received testosterone in different doses as therapy [21]. Moreover, high-dose AAS abuse has been demonstrated to exert unfavourable direct and indirect effects, through AAS-associated hyperhomocysteinaemia [22], on plasma lipid levels. In a nonblinded investigation on 19 bodybuilders, short-term (8 weeks) and long-term (> 14 weeks) high dosages of AAS administration markedly reduced HDL cholesterol [23].…”

“…The contrary effects of castration on TxA2 receptor and platelet aggregation were also reported in a cross-sectional case-control study [36]. The effects of AAS on TxA2 receptor density can in part be explained by AAS-associated hyperhomocysteinemia [22,37].…”

“…Users of anabolic steroids, which are immunosuppressive, [23] feel well being and euphoria when taking the drugs. However, researchers have documented higher rates of cardiovascular disease in former users [24]. Use of corticosteroids, a first-line treatment for many autoimmune diagnoses, significantly increases relapse by a striking margin [8].…”
